Re: initial camera position in geomview

Yes -- it looks as though you can get outside hyperbolic mode
by executing the command:

    (merge camera allcams {
	camtoworld { 1 0 0 0  0 1 0 0  0 0 1 0  0 0 0 1 }
	perspective 0  fov 2.5  near -1.1 far 1.1
    })

This puts the camera(s) at the origin, gives an orthographic view,
and chooses clipping planes and field of view so as to make the
whole unit ball visible.  The camera still moves hyperbolically
even though this view looks Euclidean, so translating or flying the
camera will distort the view.  You can return to inside-hyperbolic view with:

    (progn
	(merge camera allcams { perspective 1 })
	(camera-reset allcams)
    )

Obviously you can replace "allcams" with a specific camera.
